Halstead Boiler problem HELP!

[rich.d73]

Hello


Fault on Halstead The Finest Wicks 90.

When switching power on at the boiler, as soon as the fan starts the first fuse (2amp) on the PCB is blowing every time.


Any ideas on this fault would be gratefully received.

the fan?

seriously id guess at the fan or the pump! try disconectin each one individually and makin the appropiate microswitch to see if the boiler fires without blowin the fuse

Have done the fan, not done the pump yet.

Cheers Gaz nice one.
